If you're looking for a way to spice up your boring staircase, DIYer Geert shows off a simple way to safely light up your stairwell with programmable, color changing LED strips mounted directly to the stairs.

These might come in handy if you have a long staircase with bad lighting or if you just want to save a little energy by running LED lights instead of an overhead light. The strips are mounted to the stairs and the colors are controlled by an Arduino. Next on Geert's list of improvements is adding sensors to control the color changing and animations, which should also come in handy for turning the lights on and off as you walk up the stairs. Hit up the Geert's blog post for a guide to doing it yourself.
